Tankless Water Heaters – The Pros and Cons of Upgrading to a Tankless Unit

When it comes to upgrading your home’s water heating system, tankless water heaters are a modern, efficient option worth considering. But are they the right choice for you? First we’ll go over the two main types of tankless water heaters. Then, we’ll dive into the pros and cons of switching to a tankless unit.

There are two main types of tankless water heaters: Gas and Electric.

Gas tankless water heaters use natural gas or propane as a fuel source to heat water. They typically offer higher flow rates, making them suitable for larger homes or households with high hot water demand. However, they utilize a different venting system than a traditional tank-style unit.

Electric tankless water heaters, on the other hand, are simpler to install since they don’t require venting. They use electric elements to heat the water and are ideal for smaller homes or point-of-use applications. While generally more affordable upfront, they may not provide the same flow rate as gas models, especially in colder climates where incoming water temperatures are lower.

Choosing between gas and electric tankless water heaters depends on factors like the size of your home, hot water demand required, and your available energy sources.

The Pros of Tankless Water Heaters

Endless Hot Water:

Traditional tank-style heaters store a finite amount of hot water, which can run out if multiple people are using water simultaneously. Tankless water heaters provide a continuous supply since they heat water on demand, meaning you’ll never have to worry about a cold shower again.

Energy Efficiency:

Tankless water heaters are significantly more energy-efficient than conventional tanks because they don’t constantly reheat water. Gas tankless water heaters, in particular, can reach energy efficiency rates of up to 99%, potentially saving you $200 to $400 annually on your utility bills. Electric models, are much less efficient than their gas counterparts, but still offer considerable savings compared to traditional tank-style water heaters.

Longevity:

Given proper maintenance, the average tankless water heater lasts around 15 to 25 years, outlasting traditional units by a significant margin. Gas tankless units are especially durable, offering reliable hot water service for many years with fewer maintenance concerns compared to electric models.

Space-Saving Design:

Without a bulky tank taking up space, tankless units are perfect for smaller homes or those looking to maximize utility space. You can mount them on walls, creating more room for storage or other purposes.

Reduced Risk of Water Damage:

Since tankless systems don’t store water, there’s a much lower risk of leaks or flooding, that are normally associated with traditional water heaters with tanks that can rupture.

The Cons of Tankless Water Heaters

Higher Initial Cost/Complex Installation

Upfront, tankless water heaters are more expensive to purchase and install than traditional tank-style heaters. In the case of gas models, the venting will need to be redone as gas units require different venting material than its tank-style predecessor. Also, due to re-routing of water lines to accommodate the new tankless unit, more labor and materials are needed to accomplish the job properly. In regards to electric tankless models, additional electric work may be needed such as installation of a dedicated circuit or even a panel upgrade. However, the long-term savings on utility bills and the extended lifespan of these units can offset this initial investment over time.

Limited Hot Water Output:

While tankless systems can provide endless hot water, their capacity is limited to the number of gallons per minute they can heat. This can also be affected by the incoming temperature of the water entering the unit. The cooler the water entering the unit is, the more it can affect the hot water output of the tankless unit. In times of high hot water demand, tankless water heaters may produce a lower rate of hot water output so that it may deliver the proper temperature. Larger households or businesses with high demand for hot water may require installation of multiple units to ensure adequate hot water flow for simultaneous uses (e.g., showering and laundry). However, in these situations, the venting becomes more complex, and the need for an upgraded gas line is likely.

Gas vs. Electric Tankless Water Heaters

Gas tankless water heaters tend to outperform electric models in terms of efficiency, lifespan, and cost-effectiveness. They’re ideal for larger households and provide the highest potential for energy savings. However, if you’re using solar power or live in a smaller household with limited hot water needs, electric tankless water heaters may still be a viable, eco-friendly option.

Is a Tankless Water Heater Right for You?

Upgrading to a tankless water heater can be a great investment if you’re looking for long-term savings, efficiency, and an endless hot water supply. However, the initial cost and installation complexity can be barriers for some homeowners. Weigh the pros and cons carefully, and consult a professional plumber to determine the best option for your home.
